README
======

This README describes that data released with the Planck CIB maps
in Lenz, Doré, Lagache (2019).

This covers data at 353, 545, and 857 GHz, which also corresponds to the subfolders.
In turn, each of them contains all the data for a given mask. 

For these 7 different masks, the subfolders are named based on the threshold in HI column density
and the Planck Galactic plane mask. For example, PlanckCIB/545/2.0e+20_gp20/ contains the 545 GHz
data, for the mask corresponding to NHI < 2.0e+20 and including the Planck 20% Galactic plane mask.

For each mask, the following data products are made available:

- ``cib_fullmission_hpx.fits``, Planck Fullmission CIB map, 5' FHWM, in MJy/sr
- ``cib_oddring_hpx.fits``, Planck Oddring CIB map, 5' FHWM, in MJy/sr
- ``cib_evenring.fits``, Planck Evenring CIB map, 5' FHWM, in MJy/sr
- ``dust_model.hpx.fits``, HI-based dust model, 16.2' FWHM, in MJy/sr.
- ``mask_bool.hpx.fits``, Boolean mask. It has already been applied to the CIB maps, we provide it here for convenience.
- ``mask_apod.hpx.fits``, Apodized mask, using the PyMaster cosine apodization with a 15arcmin kernel.
- ``windowfunctions.csv``, Beam window functions for various products. Bls describe beams only, Wl include the pixel window function.
- ``CIBxKappa_powerspectra.csv``, Cross power spectrum of the Fullmission CIB map and the Planck CMB lensing convergence map. Units are Jy.

In addition to that, we provide the full CIB auto and cross power spectra for 353, 545, and 857 GHz in ``Cl_CIB_T1T2.csv``.
This is derived on the NHI < 2.5e+20 mask. The units are Jy^2/sr.

Examples on how to read and work with these products are provided on https://github.com/DanielLenz/PlanckCIB
